Description
FIELD
[0001] The present disclosure relates to generating a proxy DSRC
basic safety message for unequipped vehicles.
BACKGROUND
[0002] This section provides background information related to the
present disclosure, which is not necessarily prior art.
[0003] Active safety systems based on vehicle-to-vehicle and
vehicle-to-infrastructure wireless communications, such as
dedicated short range communication (DSRC), identify potential
threats and hazards on a roadway and provide drivers with
associated alerts and warnings. To maximize the benefits of such
active safety systems, wireless communication equipment would have
to be installed in all vehicles and relevant pieces of
infrastructure, which will take many years to achieve, and may
never be fully achieved. An alternative active safety system in
which less than all vehicles and pieces of infrastructure are
equipped with DSRC would therefore be desirable.
SUMMARY
[0004] This section provides a general summary of the disclosure,
and is not a comprehensive disclosure of its full scope or all of
its features.
[0005] The present teachings include a method for generating a
message including vehicle operating parameters. The method includes
the following: measuring operating parameters of an unequipped
vehicle using monitoring equipment present on an equipped vehicle
that is proximate to the unequipped vehicle; generating at the
equipped vehicle a message including the measured operating
parameters of the unequipped vehicle; and transmitting from the
equipped vehicle to surrounding vehicles the message including the
measured operating parameters of the unequipped vehicle to inform
surrounding vehicles of the operating parameters of the unequipped
vehicle.
[0006] The present teachings further include a method for
generating one or more proxy messages including vehicle operating
parameters. The method includes receiving at a primary equipped
vehicle messages from secondary equipped vehicles, the messages
identifying positions of each one of the secondary equipped
vehicles; comparing the positions of the secondary equipped
vehicles with positions of unequipped vehicles detected by the
primary equipped vehicle for which no messages have been received;
generating at the primary equipped vehicle a proxy message for each
one of the unequipped vehicles including operating parameters of
the unequipped vehicles; and transmitting from the primary equipped
vehicle to the secondary equipped vehicles the proxy messages
generated for each one of the unequipped vehicles to inform the
secondary equipped vehicles of the operating parameters of the
unequipped vehicles.
[0007] The present teachings also include a method for generating
at least one proxy basic safety message (PBSM) having vehicle
operating parameters. The method includes the following:
identifying locations of secondary vehicles proximate to a primary
vehicle using identification equipment of the primary vehicle;
comparing positions of the secondary vehicles identified by the
primary vehicle to vehicle positions set forth in basic safety
messages (BSMs) received by the primary vehicle; designating as
secondary equipped vehicles the secondary vehicles identified by
the primary vehicle having positions that match the vehicle
positions set forth in the BSMs received by the primary vehicle;
designation as secondary unequipped vehicles the secondary vehicles
identified by the primary vehicle having positions that do not
match the vehicle positions set forth in the BSMs received by the
primary vehicle; generating at the primary vehicle the PBSM for
each one of the secondary unequipped vehicles including operating
parameters of the unequipped vehicles; and transmitting from the
primary vehicle to the secondary equipped vehicles the PBSMs to
inform the secondary equipped vehicles of the operating parameters
of the secondary unequipped vehicles.
[0008] Further areas of applicability will become apparent from the
description provided herein. The description and specific examples
in this summary are intended for purposes of illustration only and
are not intended to limit the scope of the present disclosure.
DRAWINGS
[0009] The drawings described herein are for illustrative purposes
only of selected embodiments and not all possible implementations,
and are not intended to limit the scope of the present
disclosure.
[0010] FIG. 1 illustrates a method and system according to the
present teachings for generating one or more messages including
vehicle operating parameters according to the present teachings for
vehicles not equipped with an active safety system.
[0011] Corresponding reference numerals indicate corresponding
parts throughout the several views of the drawings.
DETAILED DESCRIPTION
[0012] Example embodiments will now be described more fully with
reference to the accompanying drawings.
[0013] With reference to FIG. 1, a method and system according to
the present teachings for generating a proxy message including
vehicle operating parameters for a vehicle not equipped with an
active safety system, such as dedicated short range communication
(DSRC), is generally illustrated at reference numeral 10. A DSRC
receiver of a DSRC equipped vehicle is illustrated at reference
numeral 12. The DSRC receiver 12 is configured to receive DSRC
basic safety messages (BSM) from DSRC equipped vehicles proximate
to the primary DSRC equipped vehicle. The BSMs can include
information regarding any suitable operating parameter of the
surrounding DSRC equipped vehicles, such as one or more of the
following operating parameters of each one of the DSRC equipped
vehicles for example: GPS position data; acceleration; speed;
change in speed; throttle percentage; steering angle; and any other
suitable operating parameter.
[0014] The primary DSRC equipped vehicle further includes any
suitable equipment for detecting the positions of vehicles or
objects proximate to the primary DSRC equipped vehicle. For
example, the primary DSRC equipped vehicle may include a camera
system 14, a sonar system 16, a radar system 18, or any other
suitable vehicle or object detecting device.
[0015] Data from the DSRC receiver 12, the camera system 14, the
sonar system 16, the radar system 18, and any other suitable device
for detecting vehicles and/or objects proximate to the primary DSRC
equipped vehicle is input to a data collector 20. The data
collector 20 can be any suitable processing device, such as a
central processing unit (CPU). The data collected for each vehicle
and/or object by the data collector 20 is input to a position
comparator 22. The position comparator 22 may be any suitable
device configured to compare data collected by the data collector
20, such as a CPU. The position comparator 22 may be separate from
the data collector 20 or included with the data collector 20. For
example, the CPU of the position comparator 22 may be separate
from, or the same as, the CPU of the data collector 20.
[0016] The position comparator 22 compares the position of a
secondary DSRC equipped vehicle, based on the BSM location
information (for example) transmitted to the DSRC receiver 12 of
the primary DSRC equipped vehicle, with vehicles and/or objects
detected by the primary DSRC equipped vehicle using the primary
vehicle's on board detection systems or devices, such as the camera
system 14, the sonar system 16, and/or the radar system 18. If the
position comparator 22 identifies a match at block 24, and if at
block 28 additional BSM data is available for comparison, then the
position comparator 22 again determines whether a position match
exists at block 24. If at block 24 the position comparator 22
determines that the primary DSRC equipped vehicle detected a
vehicle or object for which no BSM data has been received, then at
block 26 the primary equipped vehicle generates a proxy BSM for the
vehicle not equipped with DSRC (unequipped vehicle). A proxy BSM
for an object can be generated as well.
[0017] The proxy BSM message includes any suitable vehicle
operating parameter information, such as GPS position data, speed,
change in speed, acceleration, etc. The vehicle operating parameter
information is measured relative to the position of the primary
DSRC equipped vehicle because the parameters are measured by the
equipped vehicle, such as by using one or more of the camera system
14, the sonar system 16, and the radar system 18. The proxy message
is transmitted by the primary equipped vehicle to surrounding
secondary DSRC equipped vehicles, such as the vehicles for which
the primary vehicle received BSMs for at the DSRC receiver 12. In
this manner, all DSRC equipped vehicles in the vicinity of the
unequipped vehicles will be aware of the position and operating
parameters of the unequipped vehicle or vehicles, and thus be able
to avoid the unequipped vehicles and continuously monitor their
location or any other suitable parameter. Proxy BSMs can also be
generated for objects, and can include any suitable information for
the objects, such as location and type for example. If no
additional vehicles or objects are detected by the primary equipped
vehicle at block 28, the operation ends at block 30.
[0018] Example embodiments are provided so that this disclosure
will be thorough, and will fully convey the scope to those who are
skilled in the art. Numerous specific details are set forth such as
examples of specific components, devices, and methods, to provide a
thorough understanding of embodiments of the present disclosure. It
will be apparent to those skilled in the art that specific details
need not be employed, that example embodiments may be embodied in
many different forms and that neither should be construed to limit
the scope of the disclosure. In some example embodiments,
well-known processes, well-known device structures, and well-known
technologies are not described in detail.
[0019] The terminology used herein is for the purpose of describing
particular example embodiments only and is not intended to be
limiting. As used herein, the singular forms "a," "an," and "the"
may be intended to include the plural forms as well, unless the
context clearly indicates otherwise. The terms "comprises,"
"comprising," "including," and "having," are inclusive and
therefore specify the presence of stated features, integers, steps,
operations, elements, and/or components, but do not preclude the
presence or addition of one or more other features, integers,
steps, operations, elements, components, and/or groups thereof. The
method steps, processes, and operations described herein are not to
be construed as necessarily requiring their performance in the
particular order discussed or illustrated, unless specifically
identified as an order of performance. It is also to be understood
that additional or alternative steps may be employed.
[0020] When an element or layer is referred to as being "on,"
"engaged to," "connected to," or "coupled to" another element or
layer, it may be directly on, engaged, connected or coupled to the
other element or layer, or intervening elements or layers may be
present. In contrast, when an element is referred to as being
"directly on," "directly engaged to," "directly connected to," or
"directly coupled to" another element or layer, there may be no
intervening elements or layers present. Other words used to
describe the relationship between elements should be interpreted in
a like fashion (e.g., "between" versus "directly between,"
"adjacent" versus "directly adjacent," etc.). As used herein, the
term "and/or" includes any and all combinations of one or more of
the associated listed items.
[0021] Although the terms first, second, third, etc. may be used
herein to describe various elements, components, regions, layers
and/or sections, these elements, components, regions, layers and/or
sections should not be limited by these terms. These terms may be
only used to distinguish one element, component, region, layer or
section from another region, layer or section. Terms such as
"first," "second," and other numerical terms when used herein do
not imply a sequence or order unless clearly indicated by the
context. Thus, a first element, component, region, layer or section
discussed below could be termed a second element, component,
region, layer or section without departing from the teachings of
the example embodiments.
[0022] Spatially relative terms, such as "inner," "outer,"
"beneath," "below," "lower," "above," "upper," and the like, may be
used herein for ease of description to describe one element or
feature's relationship to another element(s) or feature(s) as
illustrated in the figures. Spatially relative terms may be
intended to encompass different orientations of the device in use
or operation in addition to the orientation depicted in the
figures. For example, if the device in the figures is turned over,
elements described as "below" or "beneath" other elements or
features would then be oriented "above" the other elements or
features. Thus, the example term "below" can encompass both an
orientation of above and below. The device may be otherwise
oriented (rotated 90 degrees or at other orientations) and the
spatially relative descriptors used herein interpreted
accordingly.
[0023] The foregoing description of the embodiments has been
provided for purposes of illustration and description. It is not
intended to be exhaustive or to limit the disclosure. Individual
elements or features of a particular embodiment are generally not
limited to that particular embodiment, but, where applicable, are
interchangeable and can be used in a selected embodiment, even if
not specifically shown or described. The same may also be varied in
many ways. Such variations are not to be regarded as a departure
from the disclosure, and all such modifications are intended to be
included within the scope of the disclosure.
